Auto Failover VM In A Cluster When Network Disconnected


I’m not sure about you folk but I did saw this scenario happened in my customer environment who are running Windows Server 2008 R2 or Windows Server 2012 Hyper-V. When you’ve a network disconnection on the virtual switch, your VM will lose connection and client was unable to connect to the affected VM. Rest assure that our nightmare going to end soon. With Windows Server 2012 R2 (Preview), I’ve managed to locate this option. It is called “Protected network” and you can see it on VM Network | Advanced features | Protected Network.

By default, “protected network” option is enabled on the VM level. and when it’s detected a network disconnection, your VM (in the cluster ) will automatically failover to another node.
